Why teams connect Epicor ERP and Ukg Pro

Sync the workers, org structure, and cost centers that Epicor ERP and Ukg Pro share in real time, so the people Ukg Pro manages stay current in the system that runs finance and operations.

Ukg Pro is the system of record for people: who was hired, which department and location they sit in, who they report to, and how they are paid. Epicor ERP runs finance and operations, and much of what it does depends on that same information, from booking labor cost to approving an expense report to staffing a project. Where the two are bridged by re-keying or an overnight file, each side spends the day out of step, with new hires missing from the systems they need and leavers still active where they should not be.

Stacksync syncs Sales orders, Purchase orders, Jobs, Quotes in Epicor ERP with Employment Details, Job / Position History, Compensation Details, Payroll (Pay Statements, Direct Deposit, Earnings) in Ukg Pro field by field, in real time, and in both directions. You decide which system owns which fields, so the people side stays authoritative for worker data while Epicor ERP keeps its own accounting and operational detail, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Push won opportunities from the CRM into Epicor as sales orders and sync order status back.
  • 02 Mirror parts, on-hand inventory, and job status into a reporting database for shop-floor dashboards.
  • 03 Deprovision accounts by subscribing to UKG Pro termination and job-change webhook events to disable IdP and app access as changes become effective.
  • 04 Keep Configuration code tables (jobs, locations, departments, cost centers) aligned between UKG Pro and an ERP so org and cost-center hierarchies match.

Common sync patterns

Where Ukg Pro is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Ukg Pro, the matching employee record in Epicor ERP is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in Epicor ERP

A new person set up in Ukg Pro becomes an employee record in Epicor ERP in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

One org structure

Departments, cost centers, and locations that both systems reference stay in agreement, so labor cost, approvals, and reporting in Epicor ERP roll up to the same structure Ukg Pro maintains.

What you can sync between Epicor ERP and Ukg Pro

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Epicor ERP objects Ukg Pro objects How this pairing syncs
Customers Master records synced with CRM accounts so sales and the ERP agree on ownership and credit status. Employee (Person Details) Core worker record with demographics and identifiers; read by listing employee IDs then fetching each profile, and created on hire via the personnel/onboarding endpoints. Customers is specific to Epicor ERP and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Suppliers Vendor masters kept aligned with procurement and AP automation tools. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Suppliers is specific to Epicor ERP and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Parts Item masters that anchor inventory, BOM, and order line syncs. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Parts is specific to Epicor ERP and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Sales orders Created from won CRM opportunities; status and line changes sync back out. Compensation Details Effective-dated pay rate and salary; usually read into a warehouse for comp reporting and writable as new dated changes through the compensation endpoints. Sales orders is specific to Epicor ERP and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.
Purchase orders Synced with procurement systems and matched against receipts. Payroll (Pay Statements, Direct Deposit, Earnings) Pay statements, direct-deposit accounts, and earnings history; read-only pay data replicated into finance and warehouse systems for labor-cost reporting. Purchase orders is specific to Epicor ERP and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side.
Jobs Production jobs whose status feeds shop-floor dashboards and delivery-date updates. Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Jobs is specific to Epicor ERP and Terminations to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Epicor ERP and Ukg Pro

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Epicor ERP Ukg Pro Interval-based propagation

DetectionStacksync polls Epicor ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change-date fields.

DeliveryEach detected change is written to Ukg Pro through its API, with automatic retries and rate-limit backoff.

Ukg Pro Epicor ERP Sub-second propagation

DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.

DeliveryEach detected change is written to Epicor ERP through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Epicor ERP: Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments.
  • Ukg Pro: An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.

How the Epicor ERP and Ukg Pro connectors work

Epicor ERP

Integration surface
REST API (OData) over Epicor business objects, plus BAQ (Business Activity Query) endpoints
Authentication
API key combined with basic or token authentication, depending on version and deployment
Change detection
Polling on change-date fields; outbound calls can be wired through BPM directives, but there is no standard webhook subscription surface
Capabilities

Rate limits
Subject to the platform's API rate limits and per-tenant throttling on Kinetic cloud deployments

Ukg Pro

Integration surface
REST API (UKG Pro HCM REST services) with separate Onboarding and Recruiting REST APIs, plus legacy SOAP-based UKG Pro Web Services
Authentication
Core HCM REST APIs use HTTP Basic authentication with a dedicated web service account, plus a Customer API Key and a User API Key sent as headers (found under System Configuration > Security > Service Account Administration); the Onboarding and Recruiting REST APIs instead require a bearer Authorization Token from the token endpoint.
Change detection
No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters.
